 I build a janglebox on vero from this website      http://www.sabrotone.com/?cat=17
I have it working but there are some issue, it takes an agressive attach on the strings to hear it and it tails off sustain very abruptly and with a buzzing

1.What does it do, not do, and sound like?  takes agressive string attack to hear it and effect comes on abruply and it tails off sustain abruptly
]2.Name of the circuit = janglebox clone
3.Source of the circuit (URL of schematic or project) =
4.Any modifications to the circuit? Y or N  no
5.Any parts substitutions? If yes, list them. no
6.Positive ground to negative ground conversion? Y or N no
7.Turn your meter on, set it to the 10V or 20V scale. Remove the battery from the battery clip. Probe the battery terminals with the meter leads before putting it in the clip. What is the out of circuit battery voltage? => 9.26v
Now insert the battery into the clip. If your effect is wired so that a plug must be in the input or output jack to turn the battery power on, insert one end of a cord into that jack. Connect the negative/black meter lead to signal ground by clipping the negative/black lead to the outer sleeve of the input or output jack, whichever does not have a plug in it. With the negative lead on signal ground, measure the following:
Voltage at the circuit board end of the red battery lead = 9.26 v
Voltage at the circuit board end of the black battery lead =0
IC pins
1= o
2=2.90
3=2.88
4=0
5=.66
6=.69
7=9.26
8=0

Q1  c=9.26 b=2.06 e= 1.66
Q2 c=9.07 b=.69 e= .19
Q3 c=8.37 b=0  e=0
Q4 c=8.37 b=0 e=0
Q5 c=9.26 b=8.36 3=8.64
